Product Description:

The MAC112D-0-ED-4-C/130-B-2/WA612XX/S013 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. Intended for analog drive systems, the unit converts current-loop commands into precise rotary motion for positioning tables, handling modules, and other automated axes. It is suited to applications that need repeatable speed control and accurate shaft movement during continuous machine cycling. A built-in blocking brake prevents back-driving when power is removed, and integrated tachometer and encoder feedback allow the controller to monitor actual speed and shaft position during closed-loop operation.

The motor’s nominal shaft speed is 3000 rpm, giving the drive enough headroom for fast index cycles without overspeeding the magnetic circuit. Accurate mechanical alignment is supported by a 130 mm centering diameter that mates with common IEC mounting faces and helps keep shaft positioning consistent. Heat generated in the stator is removed by natural convection, so no external blower or liquid cooling circuit is required. Power enters through a connector on side B, which helps route motor leads away from moving machine parts and crowded machine frames. When the axis is held, the brake can resist up to 60 Nm of load torque, which supports vertical or cantilevered installations during shutdowns.

A heavy-duty blocking brake supports repetitive start-stop duty and helps extend the service life of the friction elements. The tachometer generator delivers 3 V/1000 rpm, providing a linear voltage signal that compatible analog controllers can process directly for speed feedback. Winding designation ED matches the motor’s electrical characteristics to compatible analog amplifiers, helping current regulation remain stable across the operating range. Frame code 112 places the unit in the 112 frame size, and the standard position feedback attachment supports either incremental or absolute encoders for different control layouts.
